Funny how things change as you get older. I once built a Range Rover for Mr Vollers that rode on 37's, with 16" 7100's (they might have been Foxes as I use them a lot and I forget) point is the thing had ridiculous travel and could drive easily off the top of our old articulation Ramp (now permanently at MAR or whatever that is now) It had all custom suspension links, axles, lockers gearing ...the thing pretty much (and still does) kick ***. It's only issue was the more built it got the more work it required in terms of maintaining and repair.
Does it go any better than the almost stock Taco he is driving now. Maybe a bit but in reality I think not, depending very much on what you want for the long term, and how you define performance.
I'm not debating the merits of what you are doing and being connected with RN as you are I'd be doing the same. This is one of those moments that I realize how frigging old I'm getting as I sound just like the old duffs that used to give me **** about my rigs and I'd give them **** back and now I sound a bit like them........and as with so many things in life I am finding that the old advice about listening to the old duffs is so true and yet so impossible (for me ) to do. I still WANT to put my Series one on 40"s.
So, my advice on this ramble is dont pay much attention to this (my comments) and keep doing what your doing and hopefully I'll still be around 15yrs from now and we can laugh around the campfire about all the silly things we did to our trucks vs. all the silly things we did in them.
That and I'm insanely jealous that you just get to work on the cool bits. I get to spend hrs doing stupid **** like making my drivers door so it will open from the outside!
I'm starting to think that cutting the roof off, while being a bit extreme, will yield a more consistent ingress / egress than the Land Rover door handle.
